Lightning, star of Final Fantasy 13, can be made a party member in sequel Final Fantasy 13-2.

Japanese magazine Weekly Famitsu (via Andriasang) reveals Lightning will appear as a DLC coliseum character in the game. Defeat her, and you can add her to your party. The coliseum battle mode includes classic Final Fantasy series bosses - Sephiroth?

Elsewhere, Square Enix plans to release "secret story episodes" for Lightning. The Japanese company will also release Final Fantasy 13-2 novels with a view to expanding the story outside of DLC. Sazh, his son and the Chocolina character will be included in DLC or novels.

Am I the only one who finds it funny that she's being classified as a monster? Just a little bit? No? Anyway...

I don't think there's anything inherently wrong with charging for story dlc, just as long as you do it correctly. There's a difference between adding on to a satisfactorily completed story and withholding portions so you can charge for them later; Square Enix seems to be resorting to the latter category.
